The lipstick vending machine is a self-service terminal that caters to female consumers. The player first chooses the desired brand and shade of lipstick using the human–machine interface; then, after the player completes the games or makes a direct payment, the selected lipstick is dispensed. The operator may use the mobile APP to set the selling prices, as well as track the sales amount and volume of each vending machine to ensure that stock is replenished in a timely manner.
